Waveshare 2-Channel(2-CH) Isolated RS485 Expansion Hat for Raspberry Pi Adopts SC16IS752+SP3485 Solution Converts SPI to RS485 with Multi Onboard Protection Circuits Data Rate up to 921600bps

Condividi:

  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
  • Adopts SC16IS752+SP3485 dual chip combination, converts SPI to RS485, data rate up to 921600bps; Allows transceiving data manually or automatically, configured by DIP switch
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
  • Onboard auto-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance; Onboard LEDs for indicating the power and transceiver status
  • Breakout SPI control pins, for connecting with host control boards like Arduino; Comes with development resources and manual (examples in C and Python),download: www.waveshare.com/wiki/2-CH_RS485_HAT

Overview

This is a 2-channel isolated RS485 expansion HAT designed for Raspberry Pi, adopts the SC16IS752+SP3485 solution, with embedded protection circuits such as power supply isolation, ADI magnetical isolation, and TVS diode, etc.

It is easy to control the 2-channel RS485 for auto transceiving via SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
